Maxillary palatal mucosa is the most frequently used donor site of the soft tissue for periodontal plastic surgery. In our study, thickness of the palatal mucosa between the mesial side of the maxillary first premolars and the distal side of the maxillary first molars was measured with a periodontal probe and an ultrasonic device in 30 young Korean adults. Using the data, the possibility of the clinical application of ultrasonic devices was evaluated. The results of this study were as follow; 1. The thickness of the palatal mucosa of the maxillary premolars is the thickest and that of the mid-palatal portion of the maxillary first molar is the thinnest. 2. The thickness of the palatal mucosal tissue increases from the gingival margin to the mid-palatal suture. 3. The measurements of the periodontal probe and the ultrasonic device revealed the strong positive correlations.

Background: The purpose of this study was to investigate a study about undergraduate students' participation in general sports. Method: A questionnaire survey was conducted on 200 students attending physical therapy at Gimcheon university students. four items of general characteristics, 2 conditions of sports for all, 2 activities of current sports for all, and 1 thing of sports for all, were extracted from the questionnaires of total 40 items. Result: In the present study, it was found that through the cross-sectional analysis of various variables related to life sports activities according to grade, sex, age and living cost level, students participated in less sports activities than other college students. And they participated in non-living sports activities such as appreciation and movie appreciation. In addition, it was found that factors such as watching sports games mainly affect the lives of women, especially with less sports activities, and men are more active at 20 to 28 years of age than those aged 20. Conclusion: These findings suggest that it is necessary to provide various opportunities to encourage the physical activities of female students and young students of the university and actively participate in sports for all.

김태우,Kim, Tae-Woo 한국정보처리학회 2000 정보처리논문지 Vol.7 No.2

본 논문에서는 MR 영상의 3차원 가시화 및 분석을 위한 단일 채널 MR 영상의 자동 뇌영역 분할 방법을 제안한다. 이 방법은 4단계의 2차원 및 3차원 처리에 의하여 뇌윤곽을 찾아낸다. 1,2단계에서는 곡선 적합을 이용한 자동 문턱치화에 의하여 머리마스크와 초기 뇌마스크를 생성한다. 3단계에서 입방보간으로 초기 뇌마스크의 3차원 볼륨을 생성하여 형태학적 연산, 연결부위 레이블링에 의하여 중기 뇌마스크를 생성한다. 최종적으로 곡선 적합에 의한 자동 문턱치화를 이용하여 뇌마스크를 정련한다. 제안한 알고리즘은 영상의 슬라이스 방향을 고려할 필요가 없고 영상이 뇌 전체를 포함하지 않아도 되며, T1, T2, PD, SPGR등 다양한 종류의 MR 영상의 자동적인 뇌영역의 분할에 유용하다. 실험에서 20세트 MR 영상에 대하여 수동분할을 기준으로 0.97 이상의 유지도를 보였다. In this paper, a novel technique is presented for automatic brain region segmentation in single channel MR image data sets for 3D visualization and analysis. The method detects brain contours in 2D and 3D processing of four steps. The first and the second make a head mask and an initial brain mask by automatic thresholding using a curve fitting technique. The stage 3 reconstructs 3D volume of the initial brain mask by cubic interpolation and generates an intermediate brain mask using morphological operation and labeling of connected components. In the final step, the brain mask is refined by automatic thresholding using curve fitting. This algorithm is useful for fully automatic brain region segmentation of T1-weighted, T2-weighted, PD-weighted, SPGR MRI data sets without considering slice direction and covering a whole volume of a brain. In the experiments, the algorithm was applied to 20 sets of MR images and showed over 0.97 in comparison with manual drawing in similarity index.

김태우,조태경,박병수,Kim Tae-Woo,Cho Tae-Kyung,Park Byoung-Soo 대한전자공학회 2005 電子工學會論文誌-SC (System and control) Vol.42 No.2

This paper presents a modified microwave radio-thermometer (MRTM) with material characteristic estimator and multiple temperature conversion tables to measure subcutaneous temperature of a living body This estimator provides a temperature retrieval unit with the data of material characteristics such as permittivity, conductivity, thickness and geometry of the living body. The temperature retrieval unit with multiple temperature conversion tables can select one of the tables and computes temperature value corresponding to measured radiation power. In the experiments, it was shown that the MRTM could reduce measurement errors of about $0.82^{\circ}C\;to\;7.68^{\circ}C$ for the cases of distilled water and mixed liquid at the temperature of $37^{\circ}C$. 본 논문은 생체의 내부 온도를 측정하기 위해서 매질 특성 추정기와 다중 온도 변환표를 갖는 수정된 마이크로파 라디오-써모미터(modified microwave radio-thermometer, MRTM)를 제안한다. 매질 특성 추정기는 생체의 유전을, 도전을, 두께, 형태와 같은 매질의 특성에 대한 데이터를 온도 검색 장치에 전달한다. 다중 온도 변환표를 갖는 온도 검색 장치는 이 변환표들 중 하나를 선택하여 측정된 방사 전력에 해당하는 온도값을 계산한다. 실험에서 MRTM은 $37^{\circ}C$의 온도에서 증류수와 혼합 용액에 대해서 $0.82\~7.68^{\circ}C$까지의 측정 오차를 줄일 수 있었다.

김태우,윤진국,우기찬,황선광,양병도,Kim, Tae-Woo,Yun, Jin-Guk,Woo, Ki-Chan,Hwang, Seon-Kwang,Yang, Byung-Do 한국정보통신학회 2016 한국정보통신학회논문지 Vol.20 No.9

본 논문에서는 고정밀 하이브리드 온 칩 온도센서를 제안하였다. 제안된 온도센서에서는 SAR 타입 온도센서와 ${\Sigma}{\Delta}$타입 온도센서를 혼합하였다. SAR 타입 온도센서는 ${\Sigma}{\Delta}$타입 온도센서 보다 온도를 찾아가는 속도가 빠르지만 오차가 발생할 확률이 높은 단점이 있고, ${\Sigma}{\Delta}$ 타입 온도센서는 SAR 타입 온도센서 보다 정확하지만 속도가 느린 단점이 있다. 제안된 온도 센서는 두개의 온도 측정방법을 혼합하여 고정밀 고속 온도측정이 가능하다. 또한, 칩 제작 후 온도 오차 값을 메모리회로에 저장하여 온도 오차를 보상하는 회로를 포함하여 온도센서를 구현하였다. 제안된 온도센서는 $0.35{\mu}m$ CMOS 공정으로 제작되었다. 온도 정확도, 소비 전력, 칩 면적은 각각 $0.15^{\circ}C$, $540{\mu}W$, $1.2mm^2$였다. This paper presents a high accuracy and fast hybrid on-chip temperature sensor. The proposed temperature sensor combines a SAR type temperature sensor with a ${\Sigma}{\Delta}$ type temperature sensor. The SAR type temperature sensor has fast temperature searching time but it has more error than the ${\Sigma}{\Delta}$ type temperature sensor. The ${\Sigma}{\Delta}$ type temperature sensor is accurate but it is slower than the SAR type temperature sensor. The proposed temperature sensor uses both the SAR and ${\Sigma}{\Delta}$ type temperature sensors, so that the proposed temperature sensor has high accuracy and fast temperature searching. Also, the proposed temperature sensor includes a temperature error compensating circuit by storing the temperature errors in a memory circuit after chip fabrication. The proposed temperature sensor was fabricated in 3.3V CMOS $0.35{\mu}m$ process. Its temperature resolution, power consumption, and area are $0.15^{\circ}C$, $540{\mu}W$, and $1.2mm^2$, respectively.

김태우,황아롬,성우제,임용곤,Kim, Tae-Woo,Hwang, A-Rom,Seong, Woo-Jae,Lim, Young-Kon 한국음향학회 2008 韓國音響學會誌 Vol.27 No.3

Signals in an underwater channel get distorted by multipath propagation. In this paper, pre-coding method is suggested which helps comprehending the signals with minimum equalization. The signals are transformed based on the knowledge of the impulse response of the channel. Proposed pre-coding method is tested by simulations based on the ray theory and through water tank experiments. In weak multipath environment, in case of an SNR of about 20 dB, BER is $10^{-3}{\sim}10^{-4}$, while in strong multipath environment, similar BER is achieved with SNR of about 30 dB. In order for the pre-coding method to be used for underwater vehicles, channel prediction method utilizing the waveguide invariant is suggested and tested. 수중 채널에서의 음파를 사용한 신호는 다중 전달 경로 현상에 의해 왜곡된다. 본 논문에서는 채널의 임펄스 응답을 바탕으로 신호를 미리 왜곡시켜 수신기에 도착했을 때 최소한의 등화만으로 신호를 받을 수 있는 선 처리 기법을 제안하였다. 그리고 음선 이론 기반 시뮬레이션과 수조 실험을 통해 제안한 기법의 성능을 검토하였다. 다중 전달 경로 현상이 약할 경우, SNR이 약 20 dB 일 때 BER이 $10^{-3}{\sim}10^{-4}$의 성능을 보였고 다중 전달 경로 현상이 심한 환경에서 SNR이 약 30 dB 일때 유사한 BER 성능을 보였다. 제안한 기법을 수중 운동체의 통신에 사용가능하도록 송수신기의 위치 변화에 따른 채널예측 기법을 제안하였고 그 성능을 검토하였다.
